As demand for atomic layer deposition equipment spreads among Chinese solar cell manufacturers, experts throughout the industry are sharing their insight on the merits of this emerging manufacturing technology. The numbers they crunch reveal tough competition for incumbent plasma-based deposition techniques. But beyond the hype, does atomic layer deposition truly offer the better deal?
Deploying commercial and industrial PV in China without subsidy is already profitable in some areas, according to a new study, but prohibitive soft costs and cheap electricity are the main barriers for such installations in areas where grid parity remains out of reach.
To develop cost-competitive solar modules the nation must adopt a phased program and set up 15 GW of silicon-ingot-to-solar-module manufacturing capacity by 2024, according to The Energy and Resources Institute.
Tariffs will be hiked down the value chain in order to encourage domestic solar manufacturing, which currently stands at just 3.2 GW for solar cells and 8.5 GW for solar modules.
Few in the industry predicted the speed at which monocrystalline technology would develop, or the impressive cost reductions it would achieve by 2019. This has left producers of multicrystalline products facing rapidly shrinking market share and struggling to compete on a cost per watt basis. Many are now turning to cast mono processes, essentially creating a monocrystalline, or ‘mono-like’ silicon ingot in a multicrystalline furnace, to reach higher efficiencies and extend equipment lifetimes.
Micro and mini grid-connected projects will also be considered. The projects—to be developed on ‘build-own-operate’ basis—can be set up anywhere in India for self-use or use by government entities at maximum fixed tariffs of Rs 3.50/kWh. Bidding will close on August 23.
The $500k order follows the delivery of two high-volume quantum-dot production systems—valued at $1 million—to support roll-to-roll printing of thin-film solar cells at Assam facility.
India’s Directorate General of Trade Remedies (DGTR) has determined that flat steel products coated with aluminium and zinc are being dumped by manufacturers in China at dumping margins of 30-50%, South Korea (20-30%) and Vietnam (10-20%). It has proposed anti-dumping duty based on the same to offset material injury to domestic manufacturers.
Bids are invited for supply of 75 Wp solar modules based on crystalline silicon technology. The modules must be made into 9×4 arrays using 36 solar cells each. Bidding will close on August 3.
